imaqGetAngle

Usage

int imaqGetAngle(PointFloat start1, PointFloat end1, PointFloat start2, PointFloat end2, float* angle);

Purpose

Returns the angle, in degrees, between two lines. The returned angle represents the rotation around start1 required so that the line from start1 to end1 is parallel with the line from start2 to end2. The following figure illustrates how the function calculates the angle between two lines.

Parameters

Name	Type	Description
start1	PointFloat	The start point of the first line.
end1	PointFloat	The end point of the first line.
start2	PointFloat	The start point of the second line.
end2	PointFloat	The end point of the second line.
angle	float*	On return, the angle, in degrees, between the lines. This parameter is required and cannot be NULL.

Return Value

Type	Description
int	On success, this function returns a non-zero value. On failure, this function returns 0. To get extended error information, call imaqGetLastError().
